( where X is the mean, t is the coefficient, and s is the mean difference error)

As a result, only 2.5% of containers might include less than 100 ml of volume, its trust coefficient could indeed be used in accordance with 95%, which is t=1.96.  

And it can take \pm \ 1.6 \ ml to have been the full value the standard infinite:  \to CI = 100 \pm (1.96 \times 1.6) \\\\

         = 100 \pm (3.136) \\\\

Consequently, if the standard error is  \pm \ 1.6 \ ml , a similar amount should be used to fill  

= 100 - 3.136 \\\\= 96.864 \ \ mL
